Vintage Virgin Mary Brooch w/ diamonds

Vintage Virgin Mary w/ colorless diamonds. Was from a wealthier family as a wedding gift. The damaged one is just to show that I have removed 2 of the diamonds before and used every test online that people can use at home to test if the diamonds are authentic or not. 1.) They sank in water. 2.) Was held under a butane touch lighter for 45 seconds and dropped directly into water with no harm done. 3.) Used a flashlight on to see reflections. Among other ways and tests. I've read a lot into details of diamonds and telling a fake from a real one and also talked with a couple of diamond consultants online. I'll add the messages from one so you can see what was said. No, I can NOT go to a store to check with a real diamond tester, but that's why I've tried every other thing possible to test, and they have passed the test every time. I truly do believe them to be real, especially since the family who left them was very wealthy. Will sell separately if you message me. Thanks.
